timediff

timediff is a Go package for printing human readable, relative time differences. Output is based on ranges defined in the Day.js JavaScript library, and can be customized if needed. It's currently used by the mergestat command-line interface.

go get github.com/hatchet-dev/timediff

import (
    "github.com/hatchet-dev/timediff"
)

str1 := timediff.TimeDiff(time.Now().Add(-10 * time.Second))
fmt.Println(str1) // a few seconds ago

str2 := timediff.TimeDiff(time.Now().Add(-3 * time.Minute))
fmt.Println(str2) // 3 minutes ago

str3 := timediff.TimeDiff(time.Now().Add(-23 * time.Hour))
fmt.Println(str3) // a day ago

str4 := timediff.TimeDiff(time.Now().Add(23 * time.Hour))
fmt.Println(str4) // in a day

str5 := timediff.TimeDiff(time.Now().Add(10 * time.Hour))
fmt.Println(str5) // in 10 hours

str := timediff.TimeDiff(time.Now().Add(-3 * time.Minute), timediff.WithLocale("pt-BR"))
fmt.Println(str) // 3 minutos atrás
